Jacob's place is great for big groups as there are 3 huge rooms each with attached bathroom. Location is good too, 5mins walk to BTS and you can get to anywhere from there. Easy to find by Grab drivers too.
2 cons though - this might not be the place for you if you're OCD with hygiene and cleanliness in the kitchen and bathrooms. The nearest convenient store is about 7mins away, next to the BTS station. There isn't one that's super close by.
